CHARLES S. BATDORF, OF BROOKLYN, NEW YORK, ASSIGNOR TO AUTOMATIC COIN-WRAPPING MACHINE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

1 '0 all. whom it may concern:

Be it known that I, CHARLES S. BATDORF, a citizen of the United States,residing at Brooklyn, county of Kings, State of New York, have inventedcertain new and useful Improvements in Automatic Stop Mechanism, ofwhich the following is a full, clear, and eXact description.

My invention relates to improvements in automatic stop mechanism whichis adapted to be used with machines for assembling and wrapping smallarticles of metal such as coins, buttons and the like, and isparticularly, but not exclusively, adapted for use with machines forassembling and wrapping coins such as that described in my copendingapplication Serial No. 331,850, filed August 2-1, 1906.

One object of the invention is to provide means for automaticallystopping the operation of the machine should any of the articles becomedisplaced as by the breaking of a stack and scattering of the articlescomposing the same, or by failure of the stacking means to operateproperly, due to the feeding of an insufficient number of articles tothe stacking mechanism, or under any other circumstances when thearticles operated upon drop beneath the machine.

A further object of my invention is to provide means for automaticallystopping the operation of the machine when the coins or other articlesare improperly fed to it or become banked up in the feeding mechanismthereof.

To these ends the invention contemplates suitable electrical contactsmounted beneath or adjacent the operative parts of the machine whereby,when the coins are improperly handled or fed, a circuit will becompleted and the stop mechanism will be thereby brought into operation.

In the embodiment of my invention herein selected for illustration, theautomatic stop mechanism to accomplish the first object comprisesbroadly certain electrical contacts and connections which will berendered operative to stop the machine when a coin or other metallicarticle is dropped to the bottom of the machine to which the mechanismis attached and comes in contact with said connections.

In the drawings, which illustrate a preferred embodiment of myinvention, Figure 1 shows a plan view of the main contact Specificationof Letters Patent.

and feed chute contact members and a diagrammatic arrangement of theelectrical connections used in conjunction therewith. Fig. 2 shows aside elevation of a coin stacking and wrapping machine with theinvention attached thereto.

In the drawings, Fig. 1, 1 indicates the contact carrying member proper,which may be composed of a sheet of leather or other suitable materialof suflicient size to underlie preferably the entire body portion of themachine with which it is used, said member having supports 2 by which itmay be supported beneath the machine, as for example in the manner of atray or apron. Upon the upper surface of the member 1, two contactcircuit wires of opposite polarity 5 and 6 are suitably secured by anysuitable means. The terminals of the con tact wires 5 and 6 are securedto binding posts 7 and 8 respectively, preferably upon the margin of thesheet. The contact wires 5 and 6 traverse the breadth of the sheet inalternate transverse loops as indicated in Fig. 1, the transverselengths of the wire 5 alternating with those of the wire 6, and saidloops are effectually insulated from each other. By following out thepaths of wires 5 and 6, it will be found that they terminate in the openends 9 and 10 respectively at the opposite side of the sheet, as

Viewed in Fig. 1, whereby the circuit is nor.

mally maintained open between the wires. The binding post 7 is connectedby means of circuit wire 11 with one contact screw 12 of a solenoid 13,while the binding screw 8 is connected by means of circuit wires 14, 15and 16 with the main circuit wire 24.

Within the solenoid 13 is mounted a slidable metal core 18, which isprovided with a stem 19 terminating in the finger piece 20 which extendsthrough the top plate 21 of the solenoid. The core 18 is of such lengthas to project when in depressed position, as shown in Fig. 1, below thecoil of the solenoid and between and in contact with the spring contactstrips 22 and 23 respectively in the circuit of the motor 27 which oporates the machine 4: and said core is so held, as by friction, that itwill remain either in the lower or upper position unless in fluenced tochange its position. The contact strip 22 is connected by means ofcircuit wire 2 1 with a suitable source of electricity conventionallyindicated as a battery 25 and by a circuit wire 26 with a motor 27 fromwhich power is derived to operate the ma chine with which the stopmechanism of my invention is to be used. Said strip 22 is also connectedwith contact screw 17. The opposite contact strip 23 is connected bycircuit wire 28 with the motor 27.

The operation of the mechanism thus far described is as follows: lViththe contact apron 1 secured in proper position beneath the body of themachine 4, as indicated in Fig. 2, the machine is started inoperationthrough the motor 27, it being understood that the core 18 of thesolenoid has been depressed by manually pressing upon the stem 19 tobring it into contact with the contact strips 22 and 23 to complete theelectrical circuit through the motor 27. If during the operation of themachine, a coin or other article upon which the machine is operating,should fall upon the apron 1 beneath the machine, the circuit from thesource of power 25 will at once be completed through the contact wires 5and 6 and through the solenoid 13, whereupon the solenoid will beexcited and the core 18 withdrawn within the same, and from between thecontact strips 22 and 23, whereby the circuit from the source ofelectricity 25 through the motor 27 will be broken and the motor andmachine stopped, and simultaneously the circuit through the solenoidwill be broken. To again start the machine, it.

will only be necessary to remove the coins or other articles from thecontact wires 5 and 6 of apron or tray 1, whereby the so lenoid circuitwill be broken and upon again depressing the core 18 the operatingcircuit of motor 27 will be restored, whereupon the operation of themachine will be resumed.

To accomplish the second object of my invention, namely, the stopping ofthe machine through improper feeding or banking up of the articles to befed to the machine, I provide the electrical terminals 29 and 30 whichare mounted preferably within the rear wall 31 of the feed chute 32(Fig. 2) of the machine, such for example as that illustrated in mycopending application No. 331,850 above referred to. These terminals 29and 30 are suitably insulated from the chute and from each other by theinsulating blocks 33 and 34. From terminals 29 Fig. l a circuit wire 35leads to the wire 11 and thence to contact screw 12 of the solenoid 13,while from electrode 30 a circuit wire 36 leads to circuit wire 15 andthence by circuit wire 16 to circuit wire 24, source of electricity 25,wire 26, motor 27, wire 28, contact strip 23, core 18, contact strip 22,to the opposite binding screw 17 of the solenoid.

WVith the parts arranged for operation as above described, namely, withthe core 18 of the solenoid depressed to form electrical and solenoid 13would serve to excite the solenoid 13 and withdraw its core 18 frombetween the contact strips 22 and 23 and thereby break the circuit fromthe source of electricity 25 to the motor 27 and thereby stop the motorand consequently the operation of the main machine. At the same time thecircuit through the solenoid will be broken as above described.

\Vhile I have here illustrated and described the preferred embodiment ofmy invention, it is to be understood that the same may be altered indetails and arrange ment of parts without departing from the spirit andscope thereof.
